SEAL.

SPECIFICATION forming part of Letters Patent No. 391,295, dated October16, 1888.

Application filed August 20, 1888. Serial No. 283,203. (No model.)

To @ZZ whom t may concern:

Be it known that l, EDWARD J. BROOKS, a citizen of the United States,and a resident of East Orange, in the State of New Jersey, have inventeda new and useful Improvement in Seals, of which the following is aspecification.

This invention is additional to my series of lead-and-tin7 seals inwhich the lead is cast fast on one end of the tin strip,7 as set forthin my specifications forming part of United States Letters Patent No.246,068, dated August 23, 1881, No. 260,279, dated June 27, 1882, andNo. 286,775, dated October 16, 1883.

The present invention consists in the combination of a sheet metal striphaving an eyelet-collar integral therewith at one end and a hole at itsother end, to which the eyelet-collar is fitted, and a soft-metal rivetcast fast in said eyeletcollar and clinched together therewith infastening the seal, whereby the rivet is protected against being cutthrough and the eyelet is protected against being unfastened withoutdetection, and at the same time there is but one part to handle inapplying the seal, and the cost of manufacture is not materially greaterthan that of seals with castin rivets not so protected.

A sheet of drawings accompanies this specification as part thereof.

Figure 1 of the drawings represents a perspective View of an improvedseal, illustrating this invention. Fig. 2 represents a magnifiedlongitudinal section through its ends as united preparatory to fasteningand stamping the seal. Figs. 3 and 4 are magnified views representingthe respective faces of the united ends of the fastened seal, and Fig. 5represents a longitudinal section through the same.

Like letters refer to like parts in the several figures.

S represents a iiexible strip of sheet metal, preferably tin,(tin-plate,) having at one end an eyelet-collar, c, integral with thestrip, and at its other end a hole, h, fitted to said eyelet-collar, andR represents a rivet of soft metal, preferably lead, cast fast withinsaid eyelet-collar c, so as to clinch therewith in fastening the seal,as aforesaid.

The eyelet-collar c need only proj ect enough in the unfastened seal(represented by Figs 1 and 2) to extend through the hole h and form asecure clinch when the seal 'is fastened, as indicated in Fig. 5. isreadily raised on tin by a single punching operation, and its raggedoriginal edge may be left untrimmed, as indicated in Figs. 1 and 2, asthe rivet-stem has a protruding end, c, which extends lengthwiseconsiderably beyond the collar c and laterally to the outercircumference of thelatter. The primary 0bjects of so extending therivet-stem are that the eyelet collar shall not complicate inserting therivet77 or uniting the ends of the seal preparatory to the fasteningoperation, as illustrated by Fig. 2, and that when both are clinched asaforesaid the lead shall completely envelop the eyelet-burr, so as to bepebbled and provided with distinguishing lettering or otherwise stampedat the fastening operation, and thus to prevent unclinching or tamperingwith the eyelet-collar without detection.

A deep central depression, d, Figs. 4c and 5, formed by theclinching-punch and having a distinguishing letter or the like stampedin its bottom, as represented by A, Fig. 4, preferably supplements theaforesaid guards against unfastening the seal without detection. Anylateral compression of the clinching would close this depression more orless and interfere with reading the mark in its bottom. The rivet-headis preferably also pebbled, and the pebbled surfaces on both sides ofthe seal are extended as close as practicable to the tin. The rivet-headand strip are also preferably further provided with appropriatelettering, as represented by XXX--Ry the strip being printed or stampedin course of manufacture and the rivet-head at the fastening operation,as set forth in my previous specifications aforesaid.

1 am aware that a distinct eyelet inclosing the rivet-stem has beenapplied to a seal-rivet before inserting it. This forms no-part of myinvention.

Having thus described said improved seal, 1 claim as my invention anddesire to patent under this specification- A collar of this height.

IOO

An improved seal composed of a flexible of the latter, substantially alshereinbefore strip of sheet metal having an eyelet-collar n specified.tegral therewith at one end and a hole fitted to said Collar at itsother end, and a soft-metal LDWARD J' BROOKS 5 rivet east fast in saideyeletcollar with its Witnesses:
